OEE: Planned Downtime and Availability

As a core metric, Overall Equipment Effectiveness or OEE has been adopted by many companies to improve operations and optimize the capacity of existing equipment.  Having completed several on site assessments over the past few months we have learned that almost all organizations are measuring performance and quality in real-time, however, the availability component of OEE is still a mystery […]

OEE for Batch Processes

We recently received an e-mail regarding OEE calculations for batch processes and more specifically the effect on down stream equipment that is directly dependent (perhaps integrated) on the batch process.  While the inquiry was specifically related to the printing industry, batch processing is found throughout manufacturing. Our more recent experiences pertain to heat treating operations where parts are loaded into […]

Benchmarking OEE

Benchmarking Systems: We have learned that an industry standard or definition for Overall Equipment Effectiveness (OEE) has been adopted by the Semi Conductor Industry and also confirms our approach to calculating and using OEE and other related metrics. The SEMI standards of interest are as follows: SEMI E10:  Definition and Measurement of Equipment Reliability, Availability, and Maintainability. SEMI E35:  Guide to Calculate Cost of Ownership […]

How OEE can improve your Inventory

Once you have established a robust OEE system, you should also be reaping benefits in other areas of your organization. We will be offering some insights into the other performance metrics such as inventory over the next few weeks. Improved availability, performance, and quality will all have an impact on your inventory and materials management processes. Inventory turns is one […]

OEE Integration: Can you fix it?

As we are all aware, inspecting or measuring parts does not change the quality of the product.   Likewise, measuring and reporting OEE alone does not solve problems or improve performance.  While it is fair to say that increased focus and measurement of any process usually results in some degree of improvement, these are typically attributed to changes in human behavior due to […]

OEE Integration – Where do We Measure OEE? – Part I

OEE Integration Part IX – Where do we measure OEE? Our recent posts have included numerous examples to calculate OEE correctly. We also discussed integration of OEE as an effective metric for managing your processes and ultimately how to analyze and use the data to improve your profitability.  We spent little time discussing where this measurement should occur.  OEE can […]

OEE: Take the Hit

The simplicity of measuring and calculating OEE is compounded by the factors that ultimately influence the end result.  Because the concept of OEE can be readily embraced by most employees, it is easy for many people to get involved in the process of making improvements. Unfortunately the variables involved with OEE, like those of many other measurement systems, fall under scrutiny.  […]

OEE and Capacity Management

Capacity – Available or Required? From a scheduling perspective it is very easy to determine how much capacity (or time) will be required to manufacture a minimum quantity of parts.  However, it is not just a matter of multiplying the Standard Cycle Time by the Quantity of Parts and dividing by the part or process OEE %. As you may recall, the availability component of […]

Improving OEE: A Hands On Approach

We have explored Overall Equipment Efficiency (OEE) from several perspectives and how it can be used as an effective performance metric.  The purpose of measuring and monitoring OEE, at a minimum, should be three fold: To ensure the current performance levels are sustained, To identify new opportunities for improvement, To assess the effectiveness of current improvement initiatives. The Culture of Continuous Improvement and […]

OEE For Dedicated – Single Part – Processes

OEE For Dedicated – Single Part – Processes Definition:  Dedicated – Single Part – Process:  A process that produces a single product or slight variations on a theme and does not require significant tooling or equipment changeover events. A single part process is the easiest application for a OEE pilot project.  The single part process also makes it easier to demonstrate […]
